Serum somatomedin activity depressed after glucagon administration in man
Abstract:
The variations in serum somatomedin (SM) activity were compared in 14 subjects after glucagon injection (1 mg im), and in 10 controls. A significant decrease in SM activity was observed 30 and 60 min after glucagon (p less than 0.01 to less than 0.001) whereas no significant change was noted in the controls. Analysis of the dose-response curves suggests that this decrease reflects depressed SM concentration. No correlation was found between the variations of growth hormone (GH), cortisol, or fatty acids and those of SM activity. The maximum variations in glycemia, insulin and SM activity occured during the same time interval. These results suggest that glucagon may play some role in the regulation of circulating SM.

Freezing Point Depression and Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...
